"So happy I worked with Magna for my issue! They came within 45 minutes of me posting on Angie's List... that has to be some kind of record. They diagnosed the issue quickly, clearly communicated what was needed and what the cost would be, and I moved forward with it. My AC was back up and running within an hour. Highly recommend! I've saved Magna Tech's phone number in my contacts and they will be the first company I call every time I have an HVAC issue."

"Excellent service from Hecomo. Technician did not try to push purchase of a new HVAC system even though there were major issues with our system, feel comfortable while talking with an advisor. Very knowledgeable, patiently, friendly and nice person, answer all my questions. Later on, we decided to replace the whole new system with fair price and wasn’t ripped off as others. Very professional and well trained technician. I will definitely use them again."

"After having a very bad experience with another HVAC company, I used them and quickly saw how the other HVAC company was over charging. I found my technician to be very knowledgeable, hardworking and honest. He repaired one AC unit and replaced the other. Would definitely recommend!"

"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."

"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

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

You can buy R-22 refrigerant for your home air-conditioning system through your local AC repair specialist, who can also refill your R-22 system as needed. You may find that the cost of R-22 has gone up due to shortages as the EPA banned this refrigerant. Ask your pro to inspect your system for any leaks or issues.

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.
