"I had them replace my entire HVAC system (furnance + AC). They did a great job through the whole process. Out of four quotes I received, they were the only ones that took the time to do a full heating and cooling load calculation for my house when they came to do an estimate in addition to making detailed measurements of our utility room to make sure anything they installed would fit. They gave me three proposals ranging from low-end, mid-range, and high end options and explained the equipment in each of them in detail, including documenting all the model numbers, efficiency ratings, and specs. What they recommended matched up with my research I did prior to receiving estimates. They were very responsive, knowledgeable, and professional so I gave them the job. The crew arrived on time, worked hard the whole day, were respectful of my house, and did not require supervision (although, they told me I was more than welcome to ask questions and watch anything they were doing). They cleaned up, explained the warranty and rebate options with all the paperwork already filled out so that all I had to do was sign--they even mailed both the warranty and rebate off for me. The whole process went great. While their prices were fair they were not the cheapest, but I have no doubt they did a great job, didn't cut corners, and will stand by their work if I experience any problems. They are a reasonably sized HVAC business and not a one-man-band shop like many places in the area, so I know they will likely still be around through the life of the warranty and are well staffed to respond to emergencies, including a 24/7 emergency service number. Overall, we're very happy with the new system and it's a huge improvement over what it replaced--both the AC and furnace are much quieter than the old units, more energy efficient, and perform better. It's been a month since the install and everything has been working fine without problems."

The man I had my previous HVAC service contract with passed away in January and, before he died, he sold his service contracts to GAC.  I learned of this in two letters I received just about the time my spring service was due, one letter from the old company, explaining the death and sale, along with a letter from GAC welcoming me.  Since they had my money I figured I?d give them a try.  I called GAC on a Monday and scheduled my spring maintenance for Thursday.  On Tuesday my A/C made a horrendous noise and I shut it off.  Called GAC to ask if we could move the visit up to Wednesday and they said ?sure?.  Tech arrived on time on Wednesday, explained that my 19 year old system might not have too many years left.  I could spend $1,000 to replace the fan motor and cross my fingers that the condenser didn't go next, or invest in a new Furnace and A/C.  He patiently answered all my questions, we went over the pros and cons, and he didn?t talk down to me (which frequently happens as I am an older woman), under the circumstances it was a wonderful experience.  While he worked up the estimate for a new system in the van I did a computer search of the company and how much a new HVAC system should cost.  I figured I could spend weeks shopping around, but I had travel scheduled for much of April and really didn?t have time for that.  I lucked out, there were several rebates available in April from Washington Gas, PEPCO and Bryant, all of which the tech explained.  I was given two proposals with two different models, I accepted GAC?s proposal on the spot and they had their Quality Assurance man in my house on Thursday taking measurements and answering my questions (he also arrived right on time).  A new Furnace and Air Conditioner were installed on Monday, the furnace passed inspection yesterday, and everything is working well.  The new system is so much quieter than my old system and it appears to be very efficient.  Everyone I worked with at GAC was wonderful, very nice, professional, answered all my questions.  The three man team who installed the system was so upbeat for a Monday morning, I was amazed.  They arrived on time and went right to work like a well oiled machine.  One started outside on the Air Conditioner while the other began tearing out the furnace, the third was floating, helping each of the others, while unloading the trucks.  They had to work in a very tight closet like space but I never heard any grumbling.  They sang along with their music, truly seemed to like each other and they answered my questions as they worked.  They didn?t seem to be bothered by the fact that I checked in on them often.  A very different experience than the one I had 19 years ago when the old system was installed!  They warned me that, because of the area was tight, it could take up to 6 hours to complete, which it did.  They started a little after 8:00 and were done by 4:00. They left the area spotless and took their time walking me through the operation of the new thermostat, how to send in for the rebates and how to call for the county inspection.  All in all, I am happy I stayed with GAC Services and would highly recommend them.

"I would highly recommend HPC Services! They responded quickly when we called for an estimate on a new heat pump. The gentlemen who were in our home installing the unit were professional and polite and very nice to our little dogs. Sergio stayed and answered all of our questions until late in the evening. They offered us a free duct cleaning and that was completed on Monday after the Friday install. Emmett worked quickly and professionally. He was so very nice and easy to talk to. I was most impressed with the fact that they offer a Veterans discount. If are looking for an amazing company for any HVAC work, I urge you to give them a call!! Karen Hamner"

Heating and Air Conditioning questions, answered by experts

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

The cost to replace an AC evaporator coil is typically between $600 and $2,500, with an average cost around $1,300 to $1,350. The price of the coil itself can range from $550 to $1,100, depending on the brand, size, and style, with professional labor adding around $700. Replacing a condenser coil is generally less expensive, costing about $800. Because this repair involves handling refrigerants, it requires a licensed AC professional. Regular inspections, which cost between $200 and $600, can help prevent costly coil replacements.

When an evaporator coil becomes faulty, it can result in various problems within your HVAC system. These problems could include reduced cooling or heating capabilities due to ice formation and obstructed airflow, along with increased energy consumption and higher bills. Additionally, a damaged coil may lead to refrigerant leaks, which are environmentally harmful and decrease overall system efficiency.

Ultimately, if not addressed right away, a bad evaporator coil can even lead to a complete failure of your HVAC system. That’s why timely repair or replacement is crucial to maintaining your family’s comfort and your HVAC’s efficiency.

If you’re looking for a portable, budget-friendly cooling solution that doesn’t require any venting or installation, a ventless AC system is a good option. Similarly, this is a great choice if you’re renting an apartment or home and aren’t allowed to make large, structural changes like installing comprehensive HVAC, or you’re in a shared space and only need to cool your own room.
