"We had an ac unit put in two years ago. It never worked quite right. He came to check situation a couple times last summer - being it was a new unit - said to leave on auto/70 and should be fine. Still would not work correctly, hot days wouldn't work at all. This year was not working at all, only HOT air would come out. Once again came this summer, added more freon, stating there must be a leak somewhere. They couldn't find leak, told us we need to replace all the copper piping to fix the not even found leak. Wanted to charge insane amount money to fix a recent unit they installed that never worked in the first place! I tried calling the business a few times with not a single call back to speak with me. Thankfully i was forced to get it checked by someone else - it was an EASY fix! The flares were never tightened and there was a welded area that we were never told was done in first place. Do not trust this place; horrible customer service, unreliable, and afraid i was almost scammed!"

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

Heating and Air Conditioning questions, answered by experts

Though it may seem redundant, you can absolutely have a central AC unit and a window AC in your home. In fact, if you place a window AC unit near your central air, it can help move the cooler air throughout your home. But doubling up on your AC methods can get pricey, so factor in cost accordingly.

If you’re looking for a portable, budget-friendly cooling solution that doesn’t require any venting or installation, a ventless AC system is a good option. Similarly, this is a great choice if you’re renting an apartment or home and aren’t allowed to make large, structural changes like installing comprehensive HVAC, or you’re in a shared space and only need to cool your own room.

HVAC quotes may be negotiable. It’s important to be upfront about what you need, your budget, and your expectations. However, your contractor must suggest repairs or the system they think is best for you, and those things may not be negotiable. So, when can you negotiate an HVAC quote? When installing a new system, you may not need to replace ductwork or install specialty items such as whole-home air purifiers. If your contractor is bidding on those items or others you don’t need or want, ask them for a quote on only the equipment and services you need.

A blockage in the ductwork may prevent air from flowing through the vent. If some rooms in your home are very hot or cold and another isn't, that can be a sign that a vent is blocked. Another sign of a blockage is a buildup of dirt or dust around the vent. In either case, a duct installer or cleaning service can investigate the issue for you and recommend a course of action.

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.
