In August 2011 I had someone come to give me a quote. He wrote up a detailed proposal, and quoted $780. We didn't have the money until recently (Nov. 2012) to get it done. They had to have someone come and give a new proposal because the other one was old. When he guy came, he came up with a whole new proposal, which was different from the previous proposal. This was partly my fault in that I wasn't home when the new proposal was written (only my husband was home, and he had not been present during the first proposal), therefore the proposal was different than the original proposal (one vent, versus the two vents I had wanted). I easily made the corrections on the proposal, and they came on 11/2/12 to complete the work for the same $780. When I was able to review the original proposal with them, so they could understand the work I wanted to have done, it went smoothly with no hitch. Took a total of 1.5 hours. I'm pleased with the project.
Description of Work: We had some air supply brought into the basement. We had 2 vents, a return, and a transfer grill installed in our basement. There previously was no air supply in the basement.

We bought our house in May 2010 and our furnace died in November, at the first really cold snap. I called multiple places for service, but Hoffacker's was the only one who could respond same day. The system was so old and the service would have cost several hundred dollars, so we decided to replace it, something we had been hoping to put off for a couple of years. Their price was excellent, their service was excellent. They gave me options on the systems, including how to qualify for the energy-efficiency rebate. They got back to replace the system as fast as it came in. My parents had used them for decades, too, which was part of the reason we went with them. I called later for help with the programmable thermostat, and they were very gracious and helpful, walking me through something over the phone I probably could've found in a manual somewhere. They returned in the spring to check/fine tune the A/C, which wasn't possible to do in the winter.
Description of Work: I originally called for service of the system, but we decided to replace it, instead. They replaced our entire HVAC system, forced heat and A/C.

All went very well, they were here by 9:00 AM as promised and they got right to work. Three men and two trucks and estimated they'd finish by 12:00 to 12:30. Finished right on time so I could sit in on a teleconference. I think we choose the best of the bunch! Nothing shady, open and honest. A Joy to work with.

It went perfectly---from the original estimate on the phone to the installation and afterwards.y i
Description of Work: Replaced old heating and air conditioning unit. I was pleased with every aspect of Don Hoffaker's service---they were prompt, thorough, arrived to do the work when they said they would, worked diligently to install the new unit and to show me how it worked, and were polite, friendly and professional throughout. I called twice when I needed help---once when our unit stopped operating when it was very cold out---and they got back to me immediately and easily diagnosed the problem and fixed it promptly. I recommend them highly.

They have come out for service twice now for a routine cleaning and maintenance as well as a repair on the condenser drainage line. They arrived within the given window and were really quick and efficient going above and beyond with my repair to not only fixing the issue but performing an upgrade so it would not happen again. I will definitely use them in the future.

Fantastic. Don's initial person provided timely service and information. Don was then personally involved in the process once the geothermal option was selected. He located a well drilling company familiar with the area and made all necessary arrangements. The office was exceptional in keeping me informed of progress. The job took some time waiting for the drilling rig to be available but once it was all the various parts and trades were coordinated to expedite the installation and minimize the inconvenience. All providers on site were courteous, professional, and did all they could to minimize disturbance and damage to my house and property in what was a very ambitious project. The company coordinated all the permits and permissions and ensured I received all the rebates and incentives possible providing necessary paper work and guidance along the way. The end result exceeded all my expectations.
Description of Work: Installation of a geothermal hvac system to include well drilling and waste heat capture to supplement hot water. Items included a nearly 500 foot well in the backyard, underground service to the house, complete replacement of existing hvac system to include new wiring requirements, piping run through walls and ceiling to connect, and removal of all old materials.

The end of last winter, the heater stopped working. I arranged for service and they came out for repair. The diagnosis was that the built-in humidifier had leaked onto the electrical controller board for the heater and shorted it out. He fixed the furnace and turned off the humidifier, saying that when I did my fall heater inspection, their repair technician would fix the humidifier. He told me that I was lucky; it was just a few hoses and wouldn't cost much. I arranged my fall inspection and was surprised when the technician arrived without the parts. He said he would perform the $89 inspection and figure out which parts I needed. He left, saying he would order the parts and come back when they were in. I received a voicemail from them the next day stating that I needed to purchase a new unit at $480. When I called back to inquire why, the company rep said it didn't make sense to order parts (the solenoid, hoses, etc.) It would cost more than simply getting a new unit, especially given the age of the unit. I don't know how he would know how old it was since he wasn't there, but it's less than 5 years old. I said I'd get back to him. After doing a little internet research, a brand new unit (exact same model) is $257. Installation would be easy as the same unit is already there. I took him at his word that we needed the hoses and the solenoid. We ordered the parts today for $87 (including shipping). I will never use this company again. I don't like feeling like I've been scammed into buying something I didn't need.

Response from Don Hoffacker’s Air Conditioning & Heating
In response to the member's review dated as above, I offer the following: On April 3, 2012 at the request of the member, we responded for a problem with her gas furnace cycling on and off. The customer also informed the office they had just CHANGED THEIR OWN THERMOSTAT, which I am sure they did so thinking that it was their problem? A shorted circuit board was the cause of the issues, which we ordered and replaced. The technician noted that the Circuit Board Failure was most likely the result of "Water leaking from the Humidifier Unit" located above. He unplugged the unit in order to prevent further damage to the gas furnace. He also noted that the Skuttle Humidifier would need a new Water Panel, Water Feed Tube, and most of all a new Water Solenoid Valve which was the maverick that failed and caused the circuit board failure. On September 21st the customer called to schedule an appointment for a Heating Inspection. She also requested to have her "humidifier checked as well" not explaining that this had previously been performed and that technician knew what was needed. On September 25th our Peak Heating Inspection was performed for $89 and the humidifer was again checked. The next morning, as is customary, the technician communicated his finding with our Service Manager. Our repair price, which would include the wages for our technician to drive from Germantown to Silver Spring, in a van that uses Gasoline, perform the repairs needed to an EIGHT year old humidifier as well as the "numerous additional being in business factors", would have cost the customer $265. The service manager felt that offering a new like for like unit, which now for most all manufactures, come with a five year mechanical parts warranty, would be best for this customer. The member's internet investigation, which allowed her to repair her own humidifier including shipping, was achieved for only $87. Our internedt investigation provided a fee of $58.95 for the tune up kit that included a new media pad, water distribution tray, orifice and strainer. It DID NOT indlude the maverick . . . a new Water Solenoid Valve which alone listed for $82.25! We were in no way attempting to "rip her off" as she implied, but rather do the best thing for the customer which has been, for our firm, a very active and moral practice for 35 years!

Air conditioner died over night. I called Hoffacker's first thing the next morning and they had a technician at the house within 3 hours. He was courteous, professional and diagnosed the problem quickly. He fixed the A/C within 30 minutes. He cleaned up the work site quite well. Very, very pleased.

I decided to call Don Hoffacker Heating and A/C because they installed my new air condition and heater in 2003. The person who answered when I called was bery concerned for me because I had by that time been with out hot water for almost 3 weeks and I am a senior citizen who lives by myself. They scheduled me for the next day and Tim came out and told me what needed to be done and gave me an estimate. He called to schedule me for the next morning and assured me that I would be taken care of. He was a real professional and just as nice and reassuring as could be. Sure enought - the nex moring the crew of five (Mike, Alex, Tim, Grian and Craig) showed up and every one of them were professional, kind and reassuring and said they would take care of my problem. They took care of the problem and made sure the furnace and hot water heater draft was working to allow the gas fumes to escape to the attic flue. They even told me of other problems I had that a roofer would need to repair. I would definitely refer them to anyone who has a problem with their heating or air conditioning. You can't imagine how much I respect and admire those guys and trust that they will do a top rate job.
Description of Work: I had an amazing experience with Don Hoffacker Air Conditioning & Heating, Inc. in repairing a vent pipe and a cracked elbow in my attic. I had been smelling a noxious odor for a period of time - after using either my dishwasher or my washing machine. It got so bad that I called a number of different companies - and was told I needed to have a Plumber, a roofer, a chimney company, or a HVAC heating and a/c company. I called several and no one wanted to touch it. I called a roofer and he came out see what my problem was and said in the attic where the fumes funnel out to a flue pipe an elbow part was cracked and he taped it up. I then called the Washington Gas Company to come out when the fumes got so bad. The Washington Gas Company checked the hot water heater and he said my heater was burning a yellow flame and i needed to get a professional out to take care of it and he turned the water heater off. I felt I was getting the run around and didn't know what to do. I also was worried because I had such a bad experience in replacing my roof 12 years ago so it was difficult to trust anyone to fix the problem correctly.

We called on a Thursday after 5 thinking we wouldn't get a response until Friday but someone called us back Thursday night and a technician came out Friday morning. We were given a 2 hour window and the technician was punctual. He was thorough and we never felt like we were forced to pay for something we didn't need.
Description of Work: Our a/c was no longer blowing cold air. A fuse had to be replaced and freon was added.

From the moment we called, we were made to feel very well taken care of. They were very responsive and we were able to get someone to come out the next day. The guy who came to our house was very friendly and respectful. He explained and showed us everything. He was very patient and answered the 1000 questions we had, even those that were not directly related to the job on-hand. He even insisted on taking his shoes off in our house-something most people neglect to do, especially when they've been out in the mud/dirt. He was the most professional serviceman we have had. He even gave us tips and tricks to help keep our house at a more consistent temperature between all of our levels (we have 3). He showed up on time and stayed until we were content. As for the actual replacing of our unit, those guys came on time and were very professional too. They were able to finish the job in a timely manner and even hauled away our old unit free of charge. Overall, I really enjoyed the service we got and would recommend these guys to anyone. They have fair prices and do quality work. We would definitely use them again.

He was wonderful. I believe his name was Harry. We have an old system, and he brought it back to life. He not only fixed the problem but also told us how to avoid it in the future. We needed the work done on a Saturday, and the call was taken in a professional manner. They also gave us same day service. We will certainly look to them when and if we need additional service or for our new system once it finally dies. For now we are holding cool and strong.

We have no complaints as detailed above. All went very well and we are thrilled with the work done.
Description of Work: The replacement of our old airconditioning unit, furnace, waterheater, aircleaner and humidifer was exceptionally well done. The work included replacing the vents and the worn out wiring. Don Hoffacker had also maintained our "aging" system with tender care without pressuring us to replace the inefficient system we had. Our family appreciated the cleanliness of the crew given the amount of work done including hauling the old system out of the house without damaging walls or staining the carpet. Great job and I would recommend them anytime. Only challenge is the Administrative Office did not seem on top of things compared to the Technical staff.

What a thorough professional! I will definitely be calling him if/when I need hvac service again. His explanations were perfectly clear. He also advised me on a better-sized filter to use, so that it will be easier for me to remove.Turns out that any filter will allow some dust to get by. When enough dust accumulates, the tray holding the filter doesn't drain properly if the little drain pipe gets clogged. In addition to having water dripping out of the edge of the tray, water also dripped down into the box at the bottom of the unit. Mr. Hoffacker drilled a hole into the bottom of it to drain it, showed me how to flush the drain pipe every year, and left me feeling confident that I can prevent this from happening again.He did more than he had to do. With the Angie's List coupon, I feel I got a very decent price for what I gained. The fact that he came to my house at last-minute notice is VERY appreciated!
Description of Work: Mr. Hoffacker removed the filter (because it had gotten wet, it had been blown up out of its tray and was lodged out of my reach), drained the bottom part of the hvac unit, and explained everything to me. He also installed a "T" part onto the drain, so that once a year I can pour water into it and make sure the drain stays clear.

We were fortunate enough to learn that that was the issue - we thought we may have to replace the whole unit. Mike was very nice and knowledgeable and quickly recognized the issue. He went right to work and made sure the issue was resolved. He took the time to describe to me what the capacitor is and why it had to be replaced. Thank you.

Karl was a bit late, but that's because he was hold up w another client. Hoffacker keep me posted on his arrival. Everything went well, no sales or service pushing, everything was done professionally and we were very satisfied w the work done.
Description of Work: Karl, Hoffacker technician did a check on our AC unit, everything was good except it needed a new filter. He then checked the freon content and found out it was only 30% filled. The freon was pricey and we needed several pounds of it. But after that the AC unit is in perfect working order and we are satisfied with the results. Thanks Karl for your excellent work.

The employee who came to give the estomate was exceptional, provided four options to meet my needs and gave thorough explanations for each option. However, the estimated time for installment was 4-6 hours but it took 9 hours, and they did not hook up the secondary drain even though the pipe was already there. This was caught by the company's inspector and required a second visit to complete the work.

Came back from vacation and found our house was 88 degrees inside. Air was blowing but the air wasn't cold. The company office opened at 8 am, we called around 8:20 am and an efficient person promptly scheduled a technician to come between 10 am and noon on the same day. The technician (Richard) arrived between the designated time period and within an hour had completed the work. He inspected the a/c unit and found and replaced a non-working capacitor. He gave helpful maintenance tips on not only the a/c unit but also the furnace/heater. House is cool again! We got a $20 discount for being Angie's list members. We'd recommend this company again.
