"Everything went great. My AC died and it was close to 20 years old so I wanted the whole unit replaced. I have 4 young kids so no AC in the summer was not a pleasant option. The owner came out on site the day we called and was able to have the new unit installed the next day. I have dealt with many HVAC companies in the past as an Insurance Adjuster. These guys exceeded my expectations and were very reasonable on price. I highly recommend using Buric Heating and Air Conditioning!"

"Danny treated me like an old friend with helpful and timely service. It was refreshing. He inspected the unit, found a failed capacitor caused by an add-on Michael and Sons installed last inspection. Danny replaced the failed part, removed the add-on, and I was back in business in less than 30 minutes. I have a new HVAC provider!"

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 couldn't be happier with the service I received from McCrea Heating and Air Conditioning Services of Maryland. Upon returning from vacation on a 100 degree July day, I found my old HVAC system basically dead (90 degrees in my kitchen!) ... Shane immediately came out to provide an estimate, we signed a contract on the spot, and he kindly provided some freon to hold me over until the new system could be installed. Brian and Nick showed up exactly on time to install the unit, used drop cloths to protect my flooring, and were exceedingly polite and professional throughout. I'd highly recommend this organization."

"It was a pleasure hiring Sean. He was able to install our new thermostat which involved updating the wiring and removal of a module. Another company was unable to perform these tasks to get the HVAC running but Sean quickly resolved the issue. He was very friendly, knowledgeable, and punctual. Don't miss out on hiring Simply Home services, you won't regret it."

"Moises, the company owner, is incredible. I called 5 HVAC companies to get quotes for full system replacement, and MSR was not only the most responsive, but he came out the very next day. He gave me an incredibly competitive and fair quote for my project, and we immediately gave him our business. Unfortunately, our AC died before he could do the work, but he came out to our house at 6pm on a Friday to drop off a portable AC unit so we wouldn't sweat all night long. We thought we'd be stuck without central air for a few days, but Moises came and worked 9 hours on a Saturday to replace both our furnace and our AC unit. Afterwards, he even gave us a great price on a yearly HVAC maintenance plan. MSR is run by an honest, hard-working tradesman who understands what customers want and need. I won't hesitate to recommend him to friends or to anyone who needs HVAC work done."

Air Conditioning questions, answered by experts

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.

The cost to replace an AC unit averages around $5,900, with a typical range between $3,900 and $8,020. The final price depends on several factors, including the type and size of the air conditioner, its efficiency rating, your geographic region, and labor costs for installation. Smaller units like portable and window ACs are much less expensive, costing between $90 and $550, compared to central or ductless systems. If your current unit is less than 10 years old, repairing it may be more cost-effective than a full replacement.

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

When your AC contactor goes bad, you might hear chattering or buzzing noises coming from your air conditioner. You may also notice that your AC is running but isn’t cooling your home. In some cases, your air conditioner might not even turn on at all. There could also be physical damage, discoloration, or corrosion around the contactor.

The right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.
