Working as a team, Moon Services, Inc. is here to answer all of your home and commercial heating, cooling and ventilation needs, from installation to repair and continued maintenance. We hire only experienced contractors and run stringent background checks. We guarantee that the system(s) we have installed in your home will heat or cool your home as we have stated.

"After an HVAC failure I chose Moon to replace my entire system. John sold me a system based on the specs he thought would be a better fit. I was concerned about going with a small ton system for the A/C but John assured me it would handle it. Heating was great but the A/C unit was indeed a bit too small to handle the high ceilings and sun exposures of the mid summer sun. I think all of Moon's top notch experienced techs at one time or another were at my house almost weekly or biweekly because the system wasn't keeping the house cool. My electric bills were insane and because I finally had to revert to adding window units to assist the A/C. They worked endlessly that summer and I'm sure the mere mention of my name was frustrating for them and I felt bad but it was a huge issue. Moon was super fair and honest with me not charging me for one of those visits and ultimately replacing the 3ton A/C with the original sized 4ton system at no charge at all to me. I thought that was pretty amazing and it showed incredible integrity and never once were they not there for me with additional returns due to a difficult venting installation and correction. I can't say enough about how they stand by their work. All I can say is impressive. I waited a bit to write this as this was my first full season of the summer heat with the new system and it worked wonderfully. I do what Paul instructed, to let the upstair get cool first before the downstairs is adjusted. Really very grateful and appreciative for everyone's help including the girls who were always kind, considerate and sympathetic to my issues. They will always have my gratitude."

When you need AC heating or plumbing services, look no further than Horizon Services. For nearly 30 years, we’ve been the trusted name in plumbing heating, and air conditioning, offering an unmatched level of service at reasonable rates.

"Less than 5 years ago, I spent in excess of $10,000 to have a new unit installed with a 10 year warranty. I should have seen the red flags from the very beginning. The sales representative told us additional vents would be installed and when the installation crew showed up, that did not happen. Fast forward to the present and I am now on my 4th phone call for an appointment this season, 3 days so far of not being able to work as I waited for a technician to come diagnose the problem. The 3rd. tech came last night and indicated that the work the other tech did was not for the root of the problem. (I was told in front of witnesses that the work needed to be done, was not covered under warranty, would cost me $367 and would fix my issues)In fact, the 3rd tech only made the issue worse by leaving our attic return unscrewed and overfilling our unit with Freon that the 4th tech had to remove from our system. Upon leaving last night I was told that everything was corrected. Today - my home is slowly creeping up in temperature (presently 80 degrees inside, while set to 72). The company keeps trying to sell me a "maintenance plan" and I keep reiterating to EVERY one who pushes it that we have been getting tune ups/cleanings elsewhere and will only use them for warranty issues since we have had NOTHING but problems with them."

Heating and air conditioning services FAQs

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an uncertified HVAC pro could lead to poor quality work, costly future expenses, and potential code violations. A certified HVAC technician tackling your home projects protects you as a homeowner.

As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.

While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.  

The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
