"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.

"If you want honest, straight-forward, complete, and competitive pricing for a new HVAC system, go to Bluestar Air Mechanical. Our 21-year old systems needed replacement and we began our quotation/search process. Amongst the 7 companies we inquired with, Bluestar had the most comprehensive explanation, set of offerings, and was patient with us as we completed our comparisons. John promptly and completely answered all of my questions ranging from installation, future usage, efficiency, and advice on what was necessary vs an accessory. Lynn at the office was prompt and courteous on all of my scheduling, dispatch, and payment inquiries. You'll get top notch quality, service, and friendliness if you work with Bluestar for your HVAC replacement needs."

Heating and Air Conditioning questions, answered by experts

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.

Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.

Many HVAC manufacturers provide warranties that encompass the cost of a new compressor, with durations ranging from 5 to 10 years, depending on the brand. These warranties cover critical components such as the compressor, condenser, connecting tubing, evaporator, and refrigerant charge. Moreover, they often include the necessary labor for replacement or repairs. Keep in mind that premium-brand compressors may offer lifetime warranty options. It's essential to note that these warranties rarely cover labor costs.

You may be able to clean mold from your air conditioner in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma.
