Mannix Heating & Cooling

The a/c unit started having problems with the compressor fan motor not starting to spin/run when the system would try to come on automatically. Being pretty handy mechanically (30+ yrs working with swimming pool systems), a little time on the Internet pointed to the run capacitor for the motor and compressor as being the likely culprit.. The system would run as long as I would spin the fan blade to get it spinning when the system was turned on. I was all ready to go pick up a new capacitor and change it, but further reading also disclosed that the temperature drop (difference between intake air temp and output air temp) for an older system (12 yrs) should be around 18 degrees. A quick check yielded half of that at 9 degrees which again suggested a low freon charge. Lacking gauges and the license to obtain freon, it was time to call in a professional.

I first called a company (Beltway Heat & A/C Service LLC) who had done a complete system change out for a neighbor a few months earlier and I had talked to the co. owner at the time as I was looking for a new a/c service co. due to having recently fired F.H. Furr, and anticipating the need for a new system given it's age. The owner made an appt. to come out the next morning, but after several text messages (NOT phone calls) from him telling me he would be there in another 1 1/2 - 2 hrs, I finally had to leave at 5 pm (having lost a 1/2 day's pay) for work and texted him to forget it. He apparently showed up shortly thereafter and texted me to say I had a bad fan motor and it needed to be replaced.
 
Late that evening I turned to Angie's List for help and came across Mannix Heating and Cooling in Reston with an across the board A rating and 53 glowing reviews. Most reviewers made it clear they were more than just a little pleased. The next morning I called and spoke with Jenny who made an appt. for that afternoon. They offered to call from the previous job, which precluded the need to wait at home, and made it easy for my significant other to come home from her job 15 mins. away. When she got there, Dan Jones (who had been complimented in several of the reviews) was there and checking out the issues. He quickly determined that my initial diagnosis/suspicions had been correct - the capacitor was bad and the freon charge was low. He replaced the capacitor, added 3 lbs. of freon, and checked for a leak. None was detected and the low charge was attributed to either age or a very tiny, slow leak - not unusual for an older system. It was suggested to take sort of a wait and see approach as opposed to a more costly pressure test as we were getting towards the end of the cooling season, and we could more conveniently examine the options later - after an inspection of the heating half of the system (30 yr. old orig.). During the entire time Dan was here, he constantly explained and demonstrated things. He also took the time to talk with me over the phone to answers some questions and concerns of mine, especially regarding the fan motor  that had been previously diagnosed as needing replacement. He assured me that it was fine for now and there was no need to replace it.

The net result? I'm writing this review a little over 2 weeks after Dan was here and the townhouse has been cool and comfortable - even on the top floor (bedrooms) which had been a bit of a struggle at times previously- AND the system is running considerably less hours to accomplish this. And it's STILL doing this after last weeks earthquake and this weekends hurricane! Ok, so maybe that was just luck, but Dan and Mannix are a great team and I enthusiastically recommend them to anyone wanting great service - both to the customer and to the equipment.

ps - thanks to all the other Angie's List reviewers that allowed me to find such a great company.

It was great.

Jorge the Mannix sales rep showed up promptly the morning after we  called and provided several options.   One was to replace the A/C and the second was to also replace the furnace and A/C unit with a more efficient system. I had trouble deciding and called the office and was connected to Jerry. Jerry spent a lot of time on the phone going over the details and explaining the different systems. Given we planned on staying in the house,  we decided on the Carrier Infinity System, which had a manufacturer's  rebate and was recommended by another contractor.
 
We signed and faxed the contract that (late) afternoon and Jorge said he would try for the next morning.  (Jorge called later and confimed)
 
At 8am the next morning Julio, Santos and Carlos showed up in the big orange Mannix truck and had the unit installed and working by 2pm. No problems.   Jerry personal came by, inspected all the work and showed us how to use the system.  I would definitely use Mannix again.  

Company was very responsive to questions, very efficient install, quote was good value, no mess left from work performed, provided overview of new equipment. 

See above

Mannix and his team were excellent.  The quote was very professionally and thoroughly done by the owner, mentioning explicitly many small details that other companies omitted.  Mannix's team performed the installation independently, but the owner came back after the installation to check to collect the money and check on the quality of the work.  I pointed out a small problem that I had with it, and he was able to fix the problem on the spot, using the tools in his truck.  Since then, I've been very satisfied with the unit and the quality of the installation.

Jerry was nice to come out a second time to make sure we agreed on the same terms.  As far as price, it wasn’t the best offer; however, it was worth investing in a startup company.  The crew worked very diligently and added the things I asked.  I liked the fact that Jerry and his crew respected my home by covered their shoes when walking around my house. 

RUBEN AND HIS CREW ARRIVED 10 MINUTES EARY FOR THE START OF THE JOB. THEY WERE VERY PROFESSIONAL. THEY WORE COVERS OVER THEIR SHOES SO AS NOT TO DIRTY MY FLOORS, IN ADDITION, THEY LAID A CANVAS DOWN AND WALKED ON IT.  RUBEN KEPT ME INFORMED ABOUT THE WORK STATUS, SHOWED ME HOW TO OPERATE THE NEW THERMOSTAT THAT WAS INSTALLED AND CLEANED UP AFTER THE WORK. I CANNOT SAY ENOUGH ABOUT THESE PEOPLE. I RECOMMEND THEM TO EVERY ONE.THE JOB WAS COMPLETE RIGHT ON TIME. THEY HAD ALL THE PARTS, DRESSED PROFESSIONALLY --CAN;T SAY ANYTHING MORE ABOUT THEM. THEY ARE THE BEST.

Dan, my service guy was great.  Knows his stuff, moves fast and is hilarious.  Highly recommend these folks.  They are articulate in communications, services are well- priced and staff are motivated to provide high quality customer service.

I called Mannix because of the 47 A reviews on Angies List.  Was able to schedule a mutually convenient time and Jerry Mannix was on time.

My first and more immediate task was to get additional runs in the basement in anticipation of a buildout that was beginning in the near future.  As we walked that job, I also explained to Jerry that both AC units had required a fair amount of freon gas last summer and at the beginning of this summer. The units were 7-8- year old builder installed units and not just a few neighbors were also having problems.  I knew that replacement was on the horizon and had been reading and pricing units so as not to be shocked. 

Jerry patiently explained the range of options and because of some attractive Carrier, Virginia and Washington Gas rebates, settled on a configuration that balanced my considerations.

We came to an agreement on Friday and his crews show up early teh following Tuesday morning and get right to it.  They were courteous, respectful of my property, knowledgeable, amazingly quiet, efficient and cleaned up after they were finished. 

Nuts to bolts, a class act.  Jerry Mannix and his employees knew what they were doing and more importantly, did it.

They did a good job for a decent price; we were expecting it to be more. They were quick and efficient. We think in the same way. They gave me discounts because they weren’t able to make it that day. They came out and made sure we got every discount that they could give us. They got the work done. I would recommend them. They did an excellent job. They gave us a number of options on price. I would use them in the future.

I called Jerry at Mannix Heating and Air Conditioning about my a/c not working since there was a leak in the system.  Jerry came to my townhouse and we discussed the options:  try to find the leak or replace the system.  Since my a/c was about 13 years old and the new systems are much more energy efficient, I decided to replace my non-working a/c.  I was very impressed with Jerry who explained the different models and I decided to go with Trane (which I previously had).  Not only did I receive a discount from the coupon on his company's web page, but I also received another discount for being a member of Angie's List!   The day of the installation,  two technicians arrived on time around  1:30 pm  and did a very professional job. They placed cloth over my carpet so as not to get anything dirty and they were very courteous.  They stayed until 6:30 pm to make sure everything was working.  I really like this company and I immediately signed a yearly maintenance contract.   

The estimator (Patrick) showed up on time and was very courteous.  He was the only one of all the estimators that visited our home that 1) covered his shoes to protect our floors; 2) opened the inside cabinet to inspect the coil and ducting; 3) took pictures and measurements prior to providing his estimate.  Later, after having all the estimates in hand, I called the office after hours to leave a message and the owner (Jerry Mannix) answered the phone and we talked.  The Mannix estimate was a few dollars higher than another one that I was considering, and when I told Jerry that I really liked his company's approach and Patrick's professionalism, Jerry matched the other offer (and with the rebates I qualified for, beat the other estimate).  Jerry then got me on the schedule for early the next week, and also talked me through the rebate application processes for both Carrier and the State of Virginia.  The team showed up on time, did a professional install of a 15 SEER variable speed unit, and provided training to my wife on the new thermostat.  The company also gave us a one year service agreement, so we'll have them out again to ensure our unit is still functioning properly next summer.  Overall, I'd recommend this company to anyone looking to replace their home a/c.

Just bought a townhouse and wanted to have my A/C and furnace checked out - Mannix was recommended by my home inspector.  What a great experience...these guys were able to come out the day I called and were very quick and helpful.  They gave helpful pointers on how to maintain and improve the equipment.  Would definitely call them if I had any future HVAC issues.

Excellent company!  Our AC went out in the middle of a 3-day holiday weekend.  We didn't notice it until we got home in the evening.  Of course every HVAC company was busy and most of them didn't even return my call.  Mannix answered the phone when I called.  They couldn't make it out that evening, which was understandable, everyone was backed up from calls that came in earlier in the day before us.  But they did say they would come out the next morning, and they did.  The called and showed up 15 minutes later.  They spent a couple hours here fixing the problem.  The company I was using before would spend 15 minutes at the house, declare the problem solved, and leave.  And then I'd be calling then again in a month to fix the problem again.  Mannix stayed at my house for over 2 hours, ON A HOLIDAY, fixing and readjusting things and then waiting 15 minutes and re-checking them again.  Very knowledeable, professional, and friendly.  I would most definately recommend them and plan to continue using them.

I requested estimates from 3 Angieslist contractors who were rated all As.  Each provided a different solution to what was best for my HVAC requirements.  Jerry explained how the HVAC system works and recommended a 2 stage 2-ton unit for optimal operation.  He was the only one who had a listing of products and costs, so I didn?t have to wonder how the costs were ?magically? computed.  He was patient and answered my questions when I called him after talking with the other two vendors and explained the differences in approaches.   

At install, Lupe lead a fantastic team.  My furnace is located in an awkward second story space, and they systematically tore out the old one and built the new one in there.  They also inclined the unit to prevent a leak should the system have a problem since the failure in the system I replaced caused water damage to my kitchen.   Lupe was also very patient in explaining to me step-by-step how my HVAC system worked, what the wires and switches were, and general things to be aware of.   Jerry stopped by during the install with all the rebate paperwork.  

For me, trust is the most important aspect when dealing with contractors ? I have total trust in Jerry and recommend him highly.  You can?t go wrong with Mannix!

I called first and the owner of the company explained how my system is designed to the letter without seeing it.  He gave me all the information I needed to either fix it myself or have him (or someone else) take a look and attempt a fix.  I decided to make an appointment to get him to look at it.  The owner himself arrived at my door the next day and fixed the problem I reported (one room not cooling/heating adequately) as well as two related problems that he discovered.  He also checked every feed/duct for every room.  As a result, my problem bedroom is no longer a problem and I fully expect my air conditioning bills to go down.  All for a very reasonable price.  He even called a few days later to make sure everything was OK.

I couldn't be happier with the work that was done.

Called Mannix early on Friday morning and they were able to come the same day. It was during a heat wave and the AC stopped working completely. Mannix staff were friendly, professional, and very helpful from start to finish. They came out that afternoon and were able to quickly see that it was a blown fuse. They fixed it about 25 minutes and tested the system to make sure that it worked. Bob was so polite and did not try to sell us any other products. We just moved and we plan on using them from now on. 

We have a Trane xe 1000 that had ran excellent over the past 11 years with no problems.  While last night Sunday,  7/3,  ~ 11:00 p.m. we noticed the a/c was not working and discovered that the outside a/c unit was not working.    We checked Angie list and decided to try Mannix Heating & Cooling.  We were expecting a voicemail message; however, to our surprise a Mannix Representative answered the phone.  She was courtesy, professional, and was able to get us an appointment for today.  We had no problem being charged the holiday/weekend fees - it's expected.  Our HVAC Specialist "Dan" called while in route as promised.  Dan attitude was upbeat and professionalism.  He diagnosed the problem as a  "bad capacitor"; replaced it and now we have a/c. During the repair work, Dan and myself, solved the world problems, discussed music, etc.  I would highly recommend Mannix and especially "Dan, the HVAC man." Actually, as a result, we are going to purchase a maintenance contract or our HVAC/Heating Central Unit to ensure it remains in great condition.  

The installation went really well.  Staff is very professional and they took great care to leave the house clean.  Mr. Mannix came at the end of the day to review the work that had been done and he helped rearranging some of the duct work and replacing the hose trunks connecting to air returns, which had been undersized. All of the extra work was done at no charge.  Mannix really wanted to make sure that I was fully satisfied.  The system works perfectly.  I really recommend Mannix.  They are a smaller player, but it is an extremely professionally run business.

My AC would not run at all and there was some ice on the inside and outside units. I was worried it would be a very expensive repair (I had neglected to replace the filter for 6 months and I?ve read that can cause damage in extreme cases). We were having a heat wave so I figured it would be difficult to find someone to come out the same day. When I called Mannix early in the morning they didn?t make any promises, they said it would depend on how long their scheduled jobs take. I got a call back around mid day saying a tech is available and can be there in a few minutes. He arrived right on time. He figured out very quickly that it was a bad thermostat. I told him that I could have replaced it myself if I had known. He didn?t give me any sales pressure to do it for me, but he said he couldn?t check out the Freon level until the system was working, so I told him to go ahead and replace it (since I was having icing I figured the Freon level really need to be checked). He charged $110 parts and labor for a nice digital thermostat.. He then checked the Freon, it needed 1 pound which was $40. I thought that wasn?t too bad because I?ve heard stories of price gouging for Freon. He checked the vent temperature (it was 50 degrees on a 90 degree day) and commented that my AC is in great condition so I was pretty happy about that.

He did talk me into getting a 1 year maintenance contract (but again there was no sales pressure) which includes 2 inspections a year and costs exactly twice as much as a single service call ($79). He counted this service as one of the 2 annual calls, so basically I ended up paying in advance for a $79 service call in the fall. I?m OK with this because it?s a good idea to have the system checked every fall and since I paid for it in advance I won?t put it off

They seem cheaper than most places, but the tech was still professional and courteous and thorough and was glad to answer my many questions.

I would definitely recommend Mannix  Heating and Cooling.

They did a very thorough job.  They did a very good job of the installation.  They were very professional.  They not only came and did the work but they also had a supervisor come and check to make sure that we were satisfied with the work after it was done.  They just did a very nice job.  I don’t think there was anything they could do better than what they did.  I don’t have anything to compare their prices to.  We would use their services again in the future.

Mannix responded the day after we called them ... and came at the appointed time. The outside unit of our 13 year old Carrier central air would not come on We had never had any service on the unit before. Dan Jones came out and made a very logical series of quick tests that led within a half hour to the culprit within the outside unit. Within the unit he had to brush out a mouse nest and a fried mouse, a zillion insects/spiders and accumulated stuff. Another half hour and he had pinpointed the problem: A burned out "contactor" which he replaced with a new spare he had on the truck. He put it all back together and tested the unit until he was satisfied it was stable. He had a really pleasant personality and answered all the technical questions that I had in a helpful and pleasant way. In the evening and weekends, Dan is a musician.BTW,

Mannix is a two man company and they are really trying to be honest and fair. They do not push new equipment on you as many of the larger firms do.

I was so impressed with the service that I signed on for an annual maintenance contract (one Fall visit to prep the heater, and one Spring visit to prep the AC ... for a cost of $179.95 ... which is included in the $373 price I mentioned above.

VERY HIGHLY RECOMMENDED

After receiving poor service and pressured sales tactics for inferior equipment by Trademasters who were used by the previous owner we contacted three other companies for estimates for repairs.  Mannix were the most responsive. They came out the next day for the inspection and estimate, provided a good estimate price and installed quality equipment the following week when temperatures reached record highs for Alexandria, VA.  Quality service provider and easy to deal with.
