"My AC failed and I had limited time to find a good solution, I made a phone call to Relax HVAC based on the online reviews and it was a great decision. Nasser came to check the situation, he gave a very detailed and comprehensive overview of the situation and provided with the options I had. I decided to replace the unit, Nasser went above and beyond to find a unit delivery service but there was nothing available over the weekend so this gentleman went for unit pick up himself and finished the installation within a day from my initial call. Moreover, the provided price was very reasonable.I can't be more happy with the outcome and highly recommend Relax HVAC"

McCrea is a family owned business that has served our area since 1936. Financing and rebates are available on Trane systems installed by McCrea. Resistrictions apply and these are limited time offers call for details. "Its hard to stop a Trane"
"We bought a new construction and McCrea installed the HVAC. Home inspection identified the heat pump was not working in Oct. 2020. McCrea identified it was due to leaking refrigerants and promise fixed the issue. Our electric bill was extremely high the following two months and the heat pump was not cooling in Spring 2021. McCrea sent technician and again repaired the system. Bought their maintenance plan. We had 4+ repairs plus regular tune up in the past two years. Last week the heat pump stopped cooling again. We are out of labor warranty and charge us with $89 diagnostic cost after membership discount. It took three days for them to send someone to check while we suffering 90F in our house. They identified the compressor dead and need replacement. They charge $1900 for labor after membership discount. Most likely cause of the compressor failure is "suicide" with assistance. Low refrigerant at beginning and over change in later repairs likely contributed the short life."

"Happy Holidays all! Please use my Holtzople (H) review to help you address your HVAC needs!
Last summer, my Trane AC unit failed. Corey W (H) was the tech that came out to the house and troubleshooted/resolved the problem (leaking refrigerant). He also advised on probability of future repairs. Sadly, the unit performed well for only a short time before failing. It was time to consider my options. Repairs were becoming more frequent and costly.
Tyler (H System Designer) visited and walked around my house inspecting my current HVAC system. We discussed repairing or replacing my ailing AC unit. He recommended replacing with a split ductless system and emailed a quote for
1. Enhanced Mitsubishi hyper heat mini split system (system)
2. Favorable financing options - low interest rates and affordable monthly payments.
The install took a week. H’s crew arrived each morning, respected my property, and worked as a team to carefully install the new system.
With gratitude,
John"

"Excellent service! I had a 26yr old A/C and Propane furnace that I wanted to update to an ALL ELECTRIC high efficiency heat pump. The price in the estimate was much higher than I was expecting, but they worked with me and brought it down considerably, provided I could accept an install slot in a couple of days due to a cancellation. Go for it, I thought! Unfortunately, it turned out that the estimator/salesman (who shall remain nameless) apparently got a bit confused and set up the equipment as a hybrid propane system - not the all-electric system that I wanted. Ugh. I only realized this when the installers had the indoor unit in place, and I saw the propane burners. Doh! So, I explained the situation to them, and they pulled the unwanted unit out and jumped through the hoops to order the correct unit and its accessories (wiring, breakers etc.), with no change to the price. They were very friendly and polite through all of this even though it meant the wasted work and that they had to come back the next day with the new IDU. Anyway, the final install all went well, and they were very friendly and respectful of the property and explained all the install details as they went (sorry Melvin, for all the pestering!) I'm very happy with the company and the installer's knowledge and professionalism. RECOMMENDED!"

Heating Oil questions, answered by experts
You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives).
Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.
Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt.
Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.
Yes, many providers offer organic or eco-friendly treatments. Confirm availability with your contractor.
There are three main types of heat pumps. An air-source heat pump system is the most common and has two parts—an indoor air handler unit and an outdoor heat pump unit. A ductless heat pump system functions similarly to an air-source heat pump system but doesn’t need ductwork to distribute the air. A geothermal heat pump system pulls heat from the ground to help heat your home.
There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.
