"Maryland Heating and Cooling is top-notch! Great prices; on-time; flexible scheduling; neat and clean, and very efficient. The entire process took 5 hours, and our AC bill is next to nothing. We'll never hesitate again to use AC on a sticky day. I highly recommend them."

"Grove Heating & Cooling came to the rescue 5/17 after another local company couldn't complete the job. We needed our heat pump/compressor moved for the installation of a patio then reconnected. The "other" company disconnected then couldn't schedule to finish even after giving them a months notice ahead of time. We found Grove and gave them a call. It was after hours and the on-call tech returned the call. He wasn't able to come out that night but made sure to call to schedule the very next morning. By noon we had service to reconnect the heat pump and 3 hours later we were up and running. Everyone at Grove were so responsive and went out of their way to make sure we felt like a priority. You can really tell why they have been in business as long as they have been with how well they treat their customers on top of being technically proficient. Our family is now a super fan and advocate for Grove. Highly Recommended! Mike"

"I called Buric (on advice of friend/neighbor) when A/C wasn't working and I asked what to expect in their charges. The guy on the phone told me they charge a flat $95 (or $99?) for driving out here. So I asked if they charge by the hour or half hour. No, he said, by the job. He couldn't give me an estimate because he didn't know what was wrong. So, a technician came out and diagnosed my unit (which blew air but didn't get cold) as old & dead and needing replacement. So, in my mind, there was really there was no job outside of replacement. In their mind, they did a job by taking 10 minutes to look at the unit and tell me there was nothing to be done for it. So, instead of charging me $99 for coming out, they charged me $230 for coming out AND telling me the unit couldn't be fixed. That irritated me. Then I asked for a bid for new system. The guy went out and talked on the phone to his boss and come back with a written bid. I later compared it with my second bid from another co. Buric's bid was higher than the company I selected, but not enough to sway me if I had liked their way of doing business. However, the previous (over)charge, which was not explained by the guy I spoke to when I first called, left such a bad taste in my mouth I couldn't go with them. So that extra $130 they made cost them around $5000. I hope it was worth it to them. BTW, if I had gone with them, they would have subtracted the $230 from the bid, but I just couldn't get past it. So, I am not saying anything about the quality of their work--it may be just fine, but I don't like the way they did business."

"Professional, diligent, excellent communications and attention to detail, It's hard to find tradesmen who you can have confidence in, But Edwin has it all. We contracted Edwin's HVAC to replace our 22 year old AC system, he provided a very prompt quotation, with two other company's in the bidding one never responded the other took a week, Work was carried out 3 days after awarding the works, Edwin arrived at the door on time and without delay proceeded to remove the existing system 7hrs later the new system was in, commissioned and handed over carried out in a very professional and excellent workmanship. Ah! I didn't mention price... Edwin's quote was 2/3's that of the competitor and didn't suggest or recommend additional un-necessary work(s) Would I hire Edwin's HVAC again - Yes without a doubt..."

"GAC services was able to come out for a same day trouble shooting appointment. Jim S arrived on time and was very courteous and professional. He was able to quickly identify the problem with the registers and dampers and able to get warm air flowing to the otherwise very cold areas of the house. In addition, Jim was able to recommend some additional services that would help me achieve the desired evenness of temperature such as an additional return and humidifier for the home. Great experienced master certified technician!"

"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."

"Relieved - that's how I would describe working with Carroll Mechanical. Ever since another company installed my furnace 6 years ago, I don't think it was ever working right. A number of companies have come over the years but nobody was able to properly diagnose the problem until Drew from Carroll Mechanical showed up. He was wonderful from the start and had over 50 years of experience in the trade. He spent the whole morning at my house running a full diagnostic, including a detailed combustion analysis plus measurement of gas pressures, duct air pressures, air temperatures, electrical readings etc.... he explained them all to me patiently like a good doctor and told me we what we needed to do - adjust supply gas pressures and increase the size of the exhaust flue to get the right air/fuel balance. Previous companies just wanted to get in and get out, but these guys took their jobs seriously and were just lovely to deal with. Insanely smart, caring, and reasonable people."

"The owner Ryan followed up with me quickly, and was able to beat the other quotes that I got by quite a bit. And they came out immediately to install the entire heat pump in a day! Couldn't be happier."

Air Conditioning questions, answered by experts

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned. 

Winterizing can still help you save money on energy costs and help prepare your AC for its work next year when you turn it back on. We suggest planning for at least some maintenance, even if winters are mild in your area.

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.

Yes, scorpions can enter a home through AC vents, especially if the system is not well-sealed. As excellent climbers, they can scale a home's exterior and squeeze through gaps as small as 1/16 of an inch. Scorpions are often attracted to the moisture around air conditioning ducts or seek cooler areas during hot weather, using vents as a pathway inside. They may slip through small openings where the duct meets the vent cover and travel within walls before emerging. To prevent this, inspect your vents, seal any gaps, and consider installing fine mesh screens.

If you’re shopping around for a rooftop AC unit, you may hear them referred to as “package units.” That’s because rooftop AC systems are all-in-one heating and cooling units that connect directly to your home’s ductwork. If your AC repair pro references a package unit, they are referring to the system on your roof.
