"Really fast and professional service when our HVAC broke in the peak of summer. Had it up and running in almost no time. My advice to first time homeowners like me in these cases is to always make sure you know what repairs and actions are being done. It'll help in regards to money."

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 called yesterday morning, got their answering service (since it was before normal business hours). The woman told me that someone from No-Frost would call me as soon as they opened for the day -- which is exactly what happened. Two hours later, I had a technician at my door. He was extremely polite and professional, and rapidly figured out what was preventing the HVAC system from heating the house. He performed the repair and explained to me what was wrong and what he was doing to correct the problem. I was very pleased with the responsiveness of the company and the competency of its technician."

Heating and Air Conditioning questions, answered by experts

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

You should plan to change your AC unit's filter every one to three months, depending on the manufacturer's recommendations. You should also clean the coils at least once per year, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule once or twice per year.

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected. 

Signs of a damaged evaporator coil include warm air from vents, frequent starts and stops without proper cooling, failure to turn on, refrigerant leaks, and unusual noises. If you suspect issues with your AC system or its components, it’s best to call an AC repair technician for proper diagnosis and repairs.
